McDermott spent four years coaching Lotulelei in Carolina, where the former Panthers defensive coordinator made the most of the first-round tackle's run-stuffing talents.

The 6-foot-2, 315-pound Lotulelei is a reliable presence, appearing in all but two games during his five-year NFL career. In Buffalo, Lotulelei will bolster a line reuniting with a familiar face in Kyle Williams, the 34-year-old tackle who struck a one-year deal worth $6 million with the Bills on Tuesday, per Rapoport. He will receive $5 million fully guaranteed, Rapoport added.

With so many needs on defense, look for the Bills to continue adding help at every level.

The Bills are also adding signing former Saints safety Rafael Bush to a two-year contract worth up to $4.5 million, per Rapoport.
